The invention relates to the field of chemical engineering, in particular to a chemical preparation storage device. The chemical preparation storage device comprises an outer shell, an exhibition structure, an end cover, a door leaf, limit structures, fixing structure, storage structures and marking structures, wherein the storage structures are used for storing chemical preparations and rotationally connected with the outer shell; the fixing structures used for fixing the chemical preparations are arranged in the storage structures; the marking structures are beneficial for looking for and storing the chemical preparations; the exhibition structure is beneficial for looking for chemical preparation compositions and cautions of the chemical preparation compositions and is arranged on the sidewall of the outer shell; and the door leaf and the outer shell are fixed through the limit structures. The storage structure of the chemical preparation storage device are beneficial for storing the chemical preparations, the space utilization efficiency of the storage structures is greatly improved, and storage and classification of the chemical preparations are more convenient; the fixing structures effectively protect the chemical preparations; the marking structures facilitates classified marking of the chemical preparations, and the storage efficiency is improved; and the exhibition structure is beneficial for inquiring the chemical preparation compositions and functions of the chemical preparation compositions.
